Restriction enzymes cleave double-stranded dna at the sites that show a particular type of symmetry: these sequences read the same on both strands and are called palindromes. which of the following sequences is not a palindrome?
a) 5′-agatct-3′
b) 5′-cctgcagg-3′
c) 5′-cctcagg-3′
d) 5′-cggccg-3′
e) 5′-ggtacc-3′

The correct answer is C) 5"-CCTCAGG-3"

Explanation:

Palindromic sequence is a that remain same when read from front side as well as from the back side.

     Such as MADAM,ROTOR

In the given question option C is not a palindromic sequence beacuse when we read from frontside it is

        5"-CCTCAGG-3"

But when we this this same sequence from the backside it becomes

      5"CCTGAGG-3"

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
